A 12-year Danish study of 1000 healthy joggers aged 20 to 86 tells yet another tale about how to extend your life: "A light jog a few times a week may help you live longer, a new study from Denmark suggests. In contrast, running too hard may have drawbacks."

Publishing their findings in the Journal of the American College of Cardiology, the researchers found that "those who jogged strenuously were just as likely to die during the study period as those who were sedentary."

So the pendulum of the latest scientific knowledge swings back once again. But never fear: A year or decade or century from now, there'll no doubt be another study ascribing long life to high-speed, pavement-pounding marathoners.

What's missing from the ever-changing brilliance of modern secular science? Just this singular fact, noted by King David in one of the many psalms he wrote to the Lord: "And in Your book they all were written, The days fashioned for me, When as yet there were none of them" (Psalm 139:16b).

This is why secular science's solutions for extending our longevity are doomed to fail. The truth is that we each have a divinely scheduled appointment with death. And nothing can possibly change it -- not even all the medications or diets or exercise regimens the world can possibly dream up.

But here's the best news: You will live forever. The only question is whereyou'll spend it.
